14. The Minor Punishment

The realization settled over Detective Shen Ziping like the cold rain that had been falling all day — quiet, persistent, impossible to ignore. There was a fifth man. Someone in the shantytown, someone close to the Chen family or to Ma Guozhu, who had told Wei Delin exactly when and where Ma would be on the night of the murders. Without that information, Cao Shigui could not have been waiting at the hovel. Without that betrayal, the chain of events that led to three deaths might never have been set in motion.

Shen sat at his small desk, the notes from Cao's interrogation spread before him, and tried to reconstruct the timeline. Ma Guozhu had decided to confront Wei sometime in the late afternoon. He had told Lu Hongwei about his plan. He had stopped at the Chen hovel on his way to the factory. And Cao had been there, waiting.

Who else had known?

He thought about the shantytown, about its crowded alleys and its thin walls and its residents who survived by knowing everything about everyone. Secrets in North Hollow were currency, traded and sold and used as leverage. Someone had seen Ma's anger, had heard his threats, had sold the information to Wei for a handful of ration coupons or a promise of better housing.

But who?

The question gnawed at him as the evening wore on. He made a list of everyone he had interviewed, everyone who had been near the Chen hovel that night, everyone who might have had contact with Wei or his intermediaries. The list was long and inconclusive. Too many people, too many motives, too many secrets that the shantytown kept close.

At midnight, he gave up on sleep and went back to the detention center.

The night-duty officer was surprised to see him — the hour was late, and the rain had turned to a freezing sleet that rattled against the windows. But Shen's credentials were still valid, and the officer let him through without protest.

Cao Shigui was awake, sitting on his cot in the same position he had been in all day. He looked up as Shen approached the bars of his cell, and his expression flickered with something that might have been surprise.

"Detective. It's late."

"I have more questions. About the night of the murders."

"I've told you everything."

"You told me what you saw and what you did. But you didn't tell me how you knew where to be. Wei sent you to intercept Ma Guozhu. How did Wei know Ma was coming?"

Cao was silent for a long moment. "I never asked. Wei gave me orders, and I followed them. That was how it worked."

"Think, Cao. Wei must have told you something. He must have said how he knew."

Cao closed his eyes, his gaunt face tightening with the effort of memory. "He said... he said he had a source. Someone in the shantytown. Someone who kept him informed about troublemakers and malcontents. He called them his little bird."

"A bird. Male? Female?"

"He never said. I got the impression it was someone who had been working for him for a long time. Someone who was paid in permits and protection. There are informants like that in every shantytown. You must know that."

Shen did know it. The police used informants too, men and women who traded information for money or favors. But Wei's informant was different — not a reluctant collaborator, but an active participant in the system of exploitation. Someone who had been feeding Wei information for years, who had probably identified vulnerable women and reported on their compliance, who had known about Chen Xiangmei and had told Wei that Ma Guozhu was a threat.

"Did Wei ever mention a name? A location? Anything that could identify this person?"

Cao shook his head slowly. "He was careful. He never talked about his sources in front of anyone. The only reason he told me about the bird was because I needed to know that the information was reliable. He wanted me to be confident that Ma would be at the hovel."

Shen turned away from the bars, his mind working through the implications. The informant was still out there. Still living in the shantytown, probably, or nearby. Still watching and listening, even with Wei in custody. And if the informant knew about Cao's surrender, about the trial, about the witnesses who were preparing to testify...

He walked back through the corridors of the detention center, his footsteps echoing in the silence. At the front desk, he used the telephone to call Inspector Liao at her temporary office.

"There's another one," he said when she answered. "An informant. Wei had someone in the shantytown feeding him information. That's how he knew Ma was coming that night. That's how he knew which women to target."

Inspector Liao was silent for a moment. "Do you have a name?"

"No. Cao called him Wei's little bird. No name, no description. But it's someone who had access to Ma Guozhu, to Chen Xiangmei, to the other women. Someone who knew their routines, their relationships, their vulnerabilities."

"Then we need to find this person before the trial. If they're still out there, they could be feeding information to whoever is left of Wei's network. They could be identifying witnesses, tracking our movements."

"I know. I'm going back to the shantytown tomorrow. Someone there must know something."

"Be careful, Detective. If this informant has been working for Wei for years, they're not going to expose themselves easily. They'll do whatever it takes to stay hidden."

The warning stayed with Shen as he walked home through the freezing sleet. The streets were empty, the lamps flickering, and every shadow seemed to hold a watching figure. He thought about the informant, about the years of betrayal, about the women who had been identified and targeted and silenced. Someone had pointed Wei toward Chen Xiangmei. Someone had told him about Ma's plan for revenge. Someone had set the whole tragedy in motion.

And that someone was still free.

The morning came grey and bitter, the sleet hardening into a crust of ice on the streets and rooftops. Shen slept for perhaps three hours, and then he pulled on his coat and walked back to North Hollow.

The shantytown was quiet, its residents huddled indoors against the cold. But Widow Gao was outside her shack as always, bundled in her patched coat, scraping ice from the stone step with a rusted knife. She looked up as Shen approached, and her weathered face creased into a frown.

"You look like you haven't slept, Policeman."

"I haven't. I need your help."

She gestured him inside, and they sat down at the rickety table. Shen told her everything — about Cao's testimony, about the informant, about the years of betrayal that had enabled Wei's predation. Widow Gao listened in silence, her hands still on the table, her eyes sharp and knowing.

"You want to know who the bird is," she said when he was finished.

"Yes. Someone in the shantytown must know. Someone must have suspected."

Widow Gao was silent for a long moment. "There have always been informants in North Hollow. People who trade information for favors. It's how some families survive. I've never asked who they are, and they've never told me. It's not something people discuss openly."

"But you have suspicions."

"I have suspicions about many things. Suspicions are not proof."

Shen leaned forward. "Three people are dead, Widow Gao. Dozens of women were exploited for years. The trial is two weeks away, and Wei's lawyers are already working to discredit every witness. If the informant is still out there, still feeding information to Wei's network, then everyone who testifies is in danger."

The old woman's eyes narrowed. "You're asking me to accuse my neighbors. People I've known for years. People who are just trying to survive, the same as everyone else here."

"I'm asking you to help me stop a monster. The same monster you've been fighting in your own way for years."

Widow Gao picked up her net and began mending it, her fingers moving with practiced precision. "There's a man named Hu Changshou. He lives near the canal, in a shack that's slightly larger than the others. He works at the textile mill — has for fifteen years. But he's never been promoted, never been given a dormitory room, never asked for a permit. He seems content to stay exactly where he is."

"Why?"

"Because Manager Wei has paid him to stay. To watch. To listen. I've seen him at odd hours, walking the alleys, noting who comes and goes. I've seen him talking to Wei's guards — Qiu, mostly, but sometimes others. He's careful, but not careful enough."

Shen felt his pulse quicken. "Why didn't you tell me this before?"

"Because you weren't asking the right questions. And because I didn't trust you. I still don't, entirely. But I trust you more than I trust Hu Changshou."

"Do you know where he lives?"

"I can show you. But be careful. If he's been Wei's informant for years, he's not going to give up his secrets without a fight."

They walked through the frozen alleys toward the canal, picking their way across patches of ice and piles of frozen refuse. The shack that Widow Gao led him to was indeed slightly larger than the others, with a proper wooden door and glass windows instead of oil paper. Smoke rose from its chimney, and a light burned inside.

Shen approached the door and knocked.

There was a long silence. Then the door cracked open, revealing a face that was narrow and wary, with small eyes that darted from Shen to Widow Gao and back again.

"Hu Changshou?" Shen said.

"What do you want?"

"I'm Detective Shen Ziping. I have questions about your relationship with Manager Wei Delin."

The door slammed shut. Shen heard the sound of footsteps inside, of something being moved or hidden. He threw his shoulder against the door, and it burst open, the cheap lock splintering from the frame.

The inside of the shack was surprisingly well-appointed — a proper bed with a thick quilt, a wooden table with a kerosene lamp, shelves lined with tins of food and bottles of rice wine. Hu Changshou was crouched in the corner, frantically feeding papers into a small iron stove.

Shen lunged across the room and pulled him away. The papers were already burning, their edges curling into ash, but he managed to salvage a handful before they were completely consumed. He threw them to the floor and stamped out the flames, then turned to face the informant.

Hu Changshou was trembling, his narrow face pale with fear. "I didn't do anything. I was just keeping warm."

"Keeping warm with documents." Shen picked up one of the half-burned pages and read what remained. It was a list of names, written in the same neat hand that had filled Wei's ledger. Women's names, with dates and notations beside them.

"These are the same records Wei kept. Copies. You were his backup."

Hu Changshou said nothing. His small eyes were fixed on Shen, calculating, desperate.

"How long have you been working for him?"

No answer.

Shen grabbed the man by the collar and hauled him to his feet. "Three people are dead because of you. Because you told Wei that Ma Guozhu was coming. You set the whole thing in motion."

"It wasn't supposed to happen like that." Hu's voice cracked. "Wei just wanted Ma frightened. He didn't tell me anyone would die."

"What did you think would happen? A frightened man, a desperate woman, a hired enforcer waiting in the darkness. Did you think it would end peacefully?"

Hu's face crumpled. "I needed the money. I needed the permits. My family —"

"Your family?" Shen looked around the shack, at the well-stocked shelves and the thick quilt and the expensive bottles of wine. "Where is your family?"

"There is no family. I'm alone. I was always alone." Hu's voice dropped to a whisper. "But I was supposed to have one. A wife. Children. Wei promised me. He said if I worked for him long enough, he would arrange a marriage, a permit, a house outside the shantytown. He said I just had to be patient."

Shen stared at the man, at his narrow face and his trembling hands and his shelves full of things he had bought with the blood of his neighbors. "How many years did you work for him? How many women did you identify?"

"Nine years. I don't know how many women. Dozens, perhaps. I stopped counting."

Shen wanted to hit him. He wanted to haul him out into the frozen alley and leave him there, broken and exposed, for the shantytown to judge. But he was a policeman, still, and there were procedures to follow. There was testimony to collect.

"You're going to tell me everything," Shen said. "Every name. Every date. Every piece of information you gave to Wei. And then you're going to testify at the trial."

"Testify? They'll kill me. Wei's people —"

"Wei's people are in custody or on the run. And if you don't testify, you'll be charged with conspiracy to commit murder. The same charge Wei is facing. The same penalty."

Hu Changshou collapsed onto his bed, his head in his hands. "I just wanted a family. I just wanted to get out of this place."

"Everyone wants to get out of this place. Most people don't destroy others to do it."

Shen collected the half-burned papers and the rest of the documents from the shack — more lists, more names, a catalog of betrayal that stretched back nearly a decade. He put Hu Changshou in handcuffs and led him out into the freezing alley, where Widow Gao was waiting.

"Is that him?" she asked.

"Yes."

The old woman looked at Hu Changshou, at his narrow face and his trembling hands and his eyes that could not meet hers. "I've known you for fifteen years, Hu. You used to help your neighbors. You used to share your food with the children. What happened to you?"

"Survival," Hu said, his voice barely audible. "Just survival."

"There's no such thing as just survival. Survival is always a choice. And you chose wrong."

She turned and walked away, back toward her shack, her patched coat flapping in the cold wind. Shen watched her go, and he felt the weight of her words settling over him. Survival was always a choice. And in North Hollow, it was a choice that people had to make every day, in a thousand small ways, and most of them had no good options to choose from.

But some choices were still wrong. Some betrayals could not be excused.

He led Hu Changshou to the police station and booked him into custody, adding his name to the list of witnesses who would testify at the trial. The procurator would decide what charges to file, but Shen knew that Hu's testimony would be essential — not just for the murder conspiracy, but for the full scope of Wei's exploitation. Hu had identified the women. Hu had told Wei who was vulnerable, who was isolated, who could be pressured without consequence.

The fifth man was found. But the trial was still two weeks away, and Shen could not shake the feeling that there were more secrets still buried in the frozen mud of North Hollow.

That night, he sat in his apartment and wrote his report, detailing everything Hu had told him. The wind moaned outside the window, and the factory chimneys still pumped their smoke into the black sky, and somewhere in the detention center, Cao Shigui and Hu Changshou and Ma Guozhu were all waiting for the same trial, the same judgment, the same uncertain future.

The trial would begin in two weeks. And Shen was beginning to understand that the truth, once uncovered, was not a single revelation but a cascade — each answer leading to more questions, each question leading deeper into the darkness that lay beneath the surface of the city.

He thought about his son, about the grave on the hillside, about the promise he had made eleven years ago. He had wanted to be a different kind of policeman. He had wanted to find the truth and hold it up to the light.

But the truth was heavier than he had imagined, and the light was harsher, and holding them both was burning him alive.
